Quite right about the spool method affecting the acceleration of the
arrow.  That's part of the reason I suggested a light (low mass, low inertia)
spool of thread be used.  The error in the results would be minimal, I would
suppose.

I expect the spool method would be just as accurate as the original method
outlined, maybe more accurate.
